"Look, my advice to you is avoid Tom Mackenzie like the plague. "(FL90.3.33)
So by imitation I made " His fancy is study philosophy." Hence comes the conclusion:"Infinitive without to can be used as a completement." What do you think of the above?
Thanks!

Not possible.

Generally this kind of bare infinitive complement is possible only where the actual words used would or could have been in the imperative mood.

Please tell me if the quotation "... is avoid ..." is acceptable? This is the point.
Thanks!

Look, my advice to you is to avoid Tom Mackenzie like the plague.

I agree with you. But the quotation is from<<Foreign Languages>>1980.3.33.which is edited by the Shanghai Foreign Languages Institution.
"The author definitely says，“ A bare infinitive can be used as complement. Here are two examples:”
(I put it from Chinese.)
"Look, my advise to you is avoid Tom Mackenzie like the plague."(George Axelrod The Seven Year Itch)"
His first example I deleted is right. From the above we can see my quotation is without spelling or punctuation mistakes.
What do you think of it?
Thanks!

The noun is spelt advice.

What do you think of it?

Not a lot. I have given the versions I prefer in post #4.
